I recently picked up a slabbed LMC and looking it over it has a pretty large die crack on the reverse. I know die cracks have no value on regular coins, but this is a proof. I was going to not pick it up but the cost was minimal. I'll post pictures later today. So the question is "Do die cracks have any extra value on proof coins?" |

I'm not sure but I'm looking forward to the images of your proof.

An eye-catching die crack on a proof might tempt someone into paying a modest premium. In my mind it's gotta be quite noticeable/striking.

That is not a die crack. That is a linear plating bubble.

Sad that the mint let a proof coin like that make it into the set. Sadder that a respected TPG gave it a 69. |

Only cost me $2, I figured I would keep it whenever I need to tell someone to buy the coin and not the slab  Edited by hfjacinto

In theory die cracks should never occur with proof coin minting, because the quality control should be much more rigorous when producing proof coins. Obviously that is not the case here. A plus for the collector.  but a minus for the Mint.  I wonder why PCGS missed the die crack. IMO, it should have been noted with the grading, so a minus for PCGS. |

I'm wondering if it is zinc rot that has/is appearing after the slabbing was done. That line IS fairly thick to be a crack isn't it?

This is a linear plating bubble, not a die crack.
There is an air bubble between the zinc core and the copper plating. I believe it's possible for oxygen in the bubble to be slowly reacting with the zinc, making the bubble progressively larger. Maybe wasn't as noticeable when slabbed?Fine.  Edited by Tanman2001

If it is zinc rot, the future of proof Zinclons looks bleak.
